Questions & Answers

Is this a genuine original part?

This is a premium quality aftermarket replacement part by Recmar, designed specifically for Yanmar engines to provide the same fit and performance as the original part at a more competitive price point.

How do I know if it is compatible?

We recommend checking your original part number or engine service manual. If your engine is a 1GM, 2GM, or 3GM series using a 105582-49200 thermostat, this is the correct replacement.

Why is the opening temperature only 42°C?

In direct raw-water cooled engines, the thermostat is designed to open at a lower temperature (approx. 42°C / 108°F). This keeps the engine temperature below 60°C to prevent salt from crystallizing and clogging the cooling passages.
